struct FSolverParameter
bool:  1
bClampToTarget
Enable clamping scale to target
bool:  1
bUpdateClampMagnitude
Update clamping length for each iteration based on how much it moved from previous iteration
float
DampingValue
Damping allows solver to reduce oscillation but it increase iteration time to converge
EJacobianSolver
JacobianSolver
Which solver to use
